Enter the total current (amps) and the number of phases into the Calculator. The calculator will evaluate the Current Per Phase. 

Current Per Phase Formula

CPP = TC / P


  • CPP is the Current Per Phase (amps/phase)
  • TC is the total current (amps)
  • P is the number of phases

To calculate Current Per Phase, divide the total current by the number of phases.

How to Calculate Current Per Phase?

The following steps outline how to calculate the Current Per Phase.

  1. First, determine the total current (amps). 
  2. Next, determine the number of phases. 
  3. Next, gather the formula from above = CPP = TC / P.
  4. Finally, calculate the Current Per Phase.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total current (amps) = 30

number of phases = 3
